• How to use the NVL function to a parameter with comma delimited values

  Gurus,

  It is confusing to me.  I am trying to use the NVL function, but the setting that I'm passing in my cursor contains multiple values with commas.  The NVL function is confused when analyzing the values.

  'Where' cursor clause...

  and nvl (sn.c_attribute1,'x@#$%') in nvl (p_desig,'x@#$%'( )

  translated parameter values...

  and nvl (sn.c_attribute1,'x@#$%') in nvl ('SPRT''GOOD' 'BAD' 'x@#$%') -NVL does not parse the value correctly

  Any idea on how to get NVL recognize 'x@#$%' , if p_desig is null?

  Thank you

  HI, Scott.

  Whenever you have a problem, please post a small example data (CREATE TABLE and only relevant columns, INSERT statements) of all the tables involved, so that people who want to help you can recreate the problem and test their ideas.

  Also post the results you want from this data, as well as an explanation of how you get these results from these data, with specific examples.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  My question is why nvl function varies from char to varchar2 data type?
  Same case expression does not change the data type.
  I insist that this is a bug of function nvl isn't - it.

  Documented behavior:
  http://download.Oracle.com/docs/CD/E11882_01/server.112/e17118/functions119.htm#SQLRF00684

  If expr1 is character data, then Oracle Database converts expr2 to the data type of expr1
  before comparing them and returns VARCHAR2 in the character set of expr1.
  

• Do I need to use the NVL function for this request?

  I seem to have some problems using the NVL function on a date. I'm trying to create a query pulls back just a date a file was sent between the sysdate and the date_sent more a minute. Here is the code I use...
  
  Oracle: 10.2 G
  

  SELECT date_sent as date_sent
  INTO    iDateSent
  FROM    tableX
  WHERE  file_id= 9999
  AND    date_sent BETWEEN sysdate AND date_sent + 1/1440; 

  Currently Output (null):

  DATE_SENT

  Desired output when date_sent is null:

  DATE_SENT
  0:0:000 0:00:00

  Note:
  date_sent column is in a normal date - same format as sysdate format.
  
  The problem I encounter is when date_sent is null, the stored procedure, I built crashes because date_sent returns a null and a null value cannot be stored in the variable 'iDateSent '. I was thinking about using the NVL function here to resolve, however, I'm not entirely sure who will work with the above query. Any thoughts?

  Hello

  you said: "desired output when date_sent is null: date_sent: 0".
  It is not possible to have a date of 'zero '.

  "and a null value cannot be stored in the variable 'iDateSent'. '.

  I do not think: If this variable is declared normally (without any not null not constrained to this topic) so that it can contain a null value. (it's 99% of the time in PL/SQL).

  I think it's that your SQL retrieves no rows, to manage what you should put an exception handler:

  begin
  SELECT date_sent as date_sent
  INTO    iDateSent
  FROM    tableX
  WHERE  file_id= 9999
  AND    date_sent BETWEEN sysdate AND date_sent + 1/1440;
  exception when NO_DATA_FOUND then
   iDateSent:=null;
  end;
  

  So what you can do if you don't want the date empty a nvl:

  return(nvl(iDateSent,sysdate));  -- or another date ...

• Why we need to create the package instead of procedure or function in Oracle

  Hello
  
  Recently, I attended an interview, they asked,
  why we must create the package instead of procedure or function in oracle. Is a specific advantage, if we create together.
  I'm not sure. can u tell me please someone.
  
  Thank you and best regards,
  Sanjeev.

  Hello

  A part of the oracle documentation.

  What is a PL/SQL Package?
  A package is a schema object which includes subroutines, variables, and logically related PL/SQL types. Packages have two parts: a specification (spec) and a body. Sometimes, the body is unnecessary. The specification is the interface to the package. It declares the types, variables, constants, exceptions, cursors, and subprograms that can be referenced from outside the package. The body defines queries for the sliders and the code for the subprogrammes.

  Benefits of the PL/SQL Packages
  Packages have a long history in software engineering, offering important characteristics for a reliable, maintainable, and reusable code, often in team for large systems development efforts.

  Modularity

  Packages allow you to logically encapsulate Associates types, elements, and subroutines in a module named PL/SQL. Each package is easy to understand, and the interfaces between packages are simple, clear and well defined. This facilitates the development of applications.

  Easier application design

  When you design an application, all you need initially is the interface information in the package specification. You can code and compile a spec without his body. Stored subprograms that reference the package can then be compiled as well. You should not set the package body entirely until you are ready to complete the application.

  Information masking

  With packages, you can specify which types, elements, and subprogrammes are (and accessible) public or private (hidden and inaccessible). For example, if a package contains four subprogrammes, three can be public and one private. The package hides the implementation of the subprogramme private so that only the package (not your application) is affected if the application changes. This simplifies maintenance and improvement. Also, by hiding the implementation details of the users, you protect the integrity of the packaging.

  Feature added

  Sliders and packed public variables persist for the lifetime of a session. They can be shared by all the subprogrammes that are running in the environment. They allow you to manage data in any of the transactions without storing in the database.

  Best performance

  When you call a subprogram packaged for the first time, the whole package is loaded into memory. Subsequent calls to related subprograms in package require no disk i/o.

  Packets stop cascading dependencies and avoid an unnecessary recompilation. For example, if you change the body of a packaged function, Oracle does not recompile other routines that call the function; These routines only depend on parameters and return value that are declared in the specification, so they are recompiled only if the specification changes.

• How do the function of Oracle database in OBIEE Administration tool

  Hi all
  I want to use an Oracle database function as a column in OBIEE (BM, presentation model). Can someone made this inOBIEE. Pointers to this is much appreicated.
  
  Thank you

  Hi user7417334,

  You cannot use the formulas in the presentation layer (not that I know well). But you can certainly use functions of oracle database in MDB layer.

  You want to use the function EVALUATE. It works like this:

  can EVALUATE (' TO_DATE (%1, %2) "AS DATE, 31 December 2009", "MM/DD/YYYY" ")

  Generic version: EVALUATE ('' AS , value1, value2, etc.)

  FUNC) is the syntax for the function you are calling. All parameters must be replaced with %, where number refers to the order in which you specify your settings.
  DATATYPE) the type of data that will allow to evaluate the function. In this case, the DATE.
  Value1) the last part of the formula is a list separated by commas of all parameters used in the function. In this case, this is the date I want to ride
  Value2) is the second parameter. You need as many times as you have referenced in your function. In this case, it is the date format.

  Good luck and if you found this post useful, please give points!

  Best regards

• Convert a MySQL function in Oracle PL/SQL

  
  Hello

  I'm trying to transfer a MySQL database in Oracle 12 c, there are a number of functions that I need to convert since I am new to Oracle and PL/SQL in particular, I would really appreciate your help for the conversion:

  CREATE FUNCTION get_customer_balance()p_customer_id INT p_effective_date DATETIME() RETURNS DECIMAL()5,2( )
  DETERMINISTIC
  READS SQL DATA
  BEGIN
  
  DECLARE v_rentfees decimal PLACES ()5,2) ; #TAXES PAID to RENT VIDEOS INITIALLY
  DECLARE v_overfees INTEGER ; #LATE FEES FOR RENTALS PREREQUISITES
  DECLARE v_payments decimal PLACES ()5,2) ; #SUM OF PREVIOUSLY MADE PAYMENTS
  
  SELECT IFNULL (SUM(film. rental_rate ),0) INTO v_rentfees
  FROM film , inventory , rental
  WHERE film . film_id = inventory . film_id
  ET inventory . inventory_id = rental . inventory_id
  AND rental . rental_date <= p_effective_date
  AND rental . Customer_ID = p_customer_id ;
  
  SELECT IFNULL (SUM(IF((TO_DAYS(rental. return_date ) - TO_DAYS(rental. rental_date )) > film. rental_duration ,

  
  ((TO_DAYS(rental. return_date ) - TO_DAYS(rental. rental_date )) - film. rental_duration ),0)),0) INTO v_overfees
  FROM rental , inventory , film
  WHERE film . film_id = inventory . film_id

  FROM payment
  
  OÙ payment . payment_date <= p_effective_date
  AND payment . Customer_ID = p_customer_id ;
  
  RETURN v_rentfees + v_overfees – v_payments ;
  END

  This means that rental.return_date and rental.rental_date are declared as a TIMESTAMP. Question is why? Return_date/rental_date store fractions of a second? In any case, assuming rental_duration is in days:

  WHEN rental.return_date - rental.rental_date > numtodsinterval (film.rental_duration, 'day')

  But the question is return_date and rental_date stores it part time too. I assumed that he didn't, and simply omitted TO_DAYS. If so, then TO_DAYS should be translated to TRUNC:

  CREATE OR REPLACE

  Get_customer_balance FUNCTION)

  p_customer_id INT,

  p_effective_date DATE)

  RETURN NUMBER

  DETERMINISTIC

  IS

  v_rentfees NUMBER (5.2); PAID #FEES RENT VIDEOS INITIALLY

  0 OTHERWISE

  END

  )

  IN v_overfees

  The RENTAL.

  inventory,

  film

  WHERE film.film_id = inventory.film_id

  AND inventory.inventory_id = rental.inventory_id

  AND rental.rental_date<=>

  AND rental.customer_id = p_customer_id;

  In forms functions/procedures and forms triggers, you cannot use the SQL commands that did not exist in the 8.0 database.

  Oracle Forms (and reports) has a full PL/SQL engine and (only) the SQL parser.

  However, form (and reports) PL/SQL engine / SQL parser is at a level that was in the Oracle 8.0 database.

• write a view with function in oracle

  Hi all

  I have a table named border, contains the borders of certain countries.

  and then I did notice, for symmetric data, which means that if I have a folder {ch, OF} I {, ch}.

  so I want another opinion, preferably with the help of functions, to show me that these results, the first view must be used, not the main table, to create this view.

  en, 1

  pl, 1

  UK, 2

  read, 2

  read, 3

  This means between these countries, we have these quantity of bordes, but we just want to see these up to 3 borders, not more.

  Thanks for your reply.

  IM using oracle 10 g and linux ubuntu 12.

  First of all, I have a table illustrating the countries

  {code}

  -File created - Sunday-November-24-2013

  --------------------------------------------------------

  -The DOF for Table BORDERS

  --------------------------------------------------------

  CREATE TABLE 'borders' ('Country1' CHAR (2), 'countries2"TANK (2), the NUMBER of 'LENGTH')

  INSERTION of REM in borders

  TOGETHER TO DEFINE

  Insert into borders (countries1, countries2, LENGTH) values ('from', 'fr', 381);

  Insert into borders (countries1, countries2, LENGTH) values ('from', 'ch', 494);

  Insert into borders (countries1, countries2, LENGTH) values ('from', 'pl', 148);

  Insert in borders (countries1, countries2, LENGTH) values ('ch', 'fr', 608);

  Insert in borders (countries1, countries2, LENGTH) values ('ch', 'it', 318);

  Insert into borders (countries1, countries2, LENGTH) values ("ch", "li", 240);

  Insert into borders (countries1, countries2, LENGTH) values ('he', 'if', 306);

  Insert into borders (countries1, countries2, LENGTH) values ('he', 'DM', 584);

  Insert into borders (countries1, countries2, LENGTH) values ('en', 'read', 549);

  Insert into borders (countries1, countries2, LENGTH) values ('en', 'of', 1000);

  Insert into borders (countries1, countries2, LENGTH) values ('pl', 'ru', 628);

  Insert in borders (countries1, countries2, LENGTH) values ('pl', 'sk', 126);

  Insert into borders (countries1, countries2, LENGTH) values ('UK', 'au', 1800);

  {code}

  and then I have a symmetrical data view:

  {code}

  SELECT B.COUNTRY1, B.COUNTRY2

  BORDERS B

  UNION

  SELECT B.COUNTRY2, B.COUNTRY1

  BORDERS B

  {code}

  Of course you can do it in a function. But why write a function where possible in SQL using the features of Oracle wrote to us ;-)

  'min way' is the key here sentence. You said... for example, we do not want {en, 3, 1000}

  Is it because that {en, a, 2} is already covering en-> of?

  In, this case may be something like this... I am sure that other members may provide the most effective solution.

  But please review these suggested solutions build further and learn SQL/capabilities in Oracle. After all, it's that you should maintain and build on this code. Play with this code and see what makes each step. You will be able to solve the problem that you encounter in yourself. Basically, it is the main objective of these forums.
